To all whom it may concern.:

Be it known that I, EDGAR C. BARNES, Jr., a citizen of the United Statesof America, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Automatic Means forWakening the Occupant of a Bed, Couch, or the Like, of which thefollowing is a specification.

The present invention relates generally to means for wakening a sleepingperson or persons at some predetermined time; andit consists brieiiy ofa bed, couch or the like having an abnormal movement or movable part, acatch holding the bed or movable part in position and an automaticallyoperative trip for the catch to loosen the latter and thus free the bedor movable part so that the latter may move into such position as towaken the occupant.

The accompanying drawings illustrate several-practical embodiments ofthe invention showing different ways of accomplishing the object sought.

In said drawings Figure 1, is a perspective view of a folding bed in itsclosed position. Fig. 2, is a sectional elevation the bed being open.Fig. 3, is a cross section of the same. Fig. 4, isl an enlarged detailof the automatic trip. Fig. 5, is an enlarged section on the line 2 ofFig. 3; and Fig. 6 is an enlarged detail of the catch. Fig. 7 is asectional elevation of a slightly modified form of the invention appliedto a larger bedstead. Fig. 8 is a cross section of the same; and Fig. 9,is a likeview illustrating the operation of the trip and catches. Fig.10 is a sectional elevation of another modified form of the invention.Fig. 11, is a partial rear vi w of the bedstead head and automatictripping device. Fig. 12, is an enlarged sectional elevation of thecatch and its trip. Fig. 13 is a side elevation of the same, thesupporting case being in section; and Fig. 14, isa detail. Figs. 15 and16 are views similar to Figs. 12 and 13, showing a slight modificationthereof with the catch indicated by dotted linesin its releasedposition.

The invention in its simplest form consists of a bedstead B adapted tomove to an abnormal position or having a movable part D adapted to movewith respect to the other portion of the bedstead; a catch L for hold-Serial No. 43 7,078. (No model.)

ing the bedstead or movable part in its normal position and a trip Wconnected with some suitable automatically operating device A, as analarm clock, by the movement of which the trip moves to release thecatch and free the bedstead or movable part so that it may drop and thuswaken the occupant.

Referring to Figs. 1 to 6, the bed bottomB forms the front of a cabinethaving a top 18 and sides and back C, the bed bottom having the usualsides 15 and head and foot pieces 14, 16, and being hinged at J to thesides of the cabinet may swing down into the position, Fig. 3, supportedby legs 17. The head portion of the bed bottom is formed by the movablepart D having an inner head piece 13 and inner side pieces 12 and hingedat H to the other portion of the bed bottom which may carry the usualbed springs S and mattress M, the spring and mattress preferably alsoformed of movable parts adapted to follow the movable part D into theposition seen in dotted lines Fig. 2. The movable part is held in itsnormal and usual position by the catch L in the form of a lever pivotedat G, to a bracket E fastened to the head piece 14, the hooked end 5 ofwhich catch Fig. 6, engages the hook 6 of a fixture K fastened to theinner head piece of the movable part D, a spring U tending to hold thetwo hooks engaged or it might be a weighted end to the lever as seen bydotted lines. The free end of the catch lever L has a cup 7 thatreceives the trip W,in the form of a weight suspended at the end of acord, chain or the like 8, the opposite end of which is connected to amovable part 9 of the alarm clock A as for instance the winding up keywhich as is well known revolves in the reverse direction when the alarmgoes off. The cord or chain 8, see Fig. 4, is connected to one of theradial arms 10 of the winding key and passes over a guide pulley Rsupported in the frame of the bed cabinet holding `the Weight inpositionto drop into the cup end of the catch lever when the automaticallyoperative device moves.

The occupant before retiring sets the alarm to operate at the desiredhour and winds up the alarm by the key 9 thereby also winding up thecord 8 and raising the trip W asin Figs. 2 and 3. At the hour s et thealarm operates,

IOC

the key rotates in the direction of the, arrow Fig. 4, unwinds the cord8 and lowers the trip. As soon as the trip meets the cup end of thecatch lever L its weight rocks said lever into the position indicated bydotted lines Fig. 3, thus disengaging the hooks and allowing the movablepart to drop suddenly down into the position indicated by dotted linesFig. 2, the force of the fall being deadened by a cushion P ot' rubberor the like, thereby suddenly disturbing the sleeper and awakening him.

In the slight modification shown in Figs. 7, 8 and 9, the bedstead is ofthe usual form instead of a folding one as in the construction justdescribed. The automatically operative device A as the alarm clock issupported by a bracket 23 fast to the headboard and the pulley R issimilarly supported. The catch lever L has a hook 21 engaging a hook 2Oon a rod F connecting two supplemental catches Z pivoted to theheadboard and each having a hook 6 to engage the hooked end of thefixture K fastened to the inner head piece of the movable part D. Vhenthe trip weight I drops onto the catch lever L it is rocked against itsstop pin 22 as in Fig. 9, releasing the connecting rod F and allowingthe spring N to rock the supplemental catches Z tree ot the xtures K sothat the movable part D is free to fall as before.

The approved form ot the invention is shown in the modification embracedby Figs. 10 to 14 inclusive; wherein the bed bottom is a four-sidedframe 12, 13, supporting the bed spring S and mattress M and mountedbetween the usual head and foot boards 14, 16 and the side pieces 15,upon substantially central pivots Il so as to tilt into the positionindicated by dotted lines Fig. l0 against the force of a spring 30. Thehead piece 13 ot the movable bed bottom as before carries a hook K borneupon bya spring 3l and forining one part of the catch, pivoted to afixture K2 projecting from said head piece, and adapted to extend upwardon the rear of the head board 16 of the bedstead. The other member ofthe catch is formed by the shoulder hub 32 of the lever L pivoted to afixture E secured to the rear ot the headboard, which lever is borneupon by a spring 33 tending to rock it down into the dotted positionseen in Fig. l2. The upper end of the lever L carries a loosely pivotedtripping arm 35 having a shoulder 36 adapted to be engaged by a pawl 37,the free end of the arm 35 being connected bya cord Sguided bya pair ofgrooved wheels 34C with a pin engaging the wind up key 9 of the alarmclockA supported on the top of the headboard. Vhen the alarm is wound upand the bed bottom is in its usual position the parts are in theposition shown by full lines Fig. 12, the cord holding the shoulder 36of the arm 35 against the pawl 37 and the latter holding the lever Lupward against the force of its spring 33.

When the alarm of the automatic device operates, the cord 8 is loosenedthus allowing the tripping arm 35 to drop and remove its shoulder fromthe pawl so that it is free to pass unobstructedly beneath the pawl asthe spring 33 then acts to rock the lever downward in the direction ofthe arrow Fig. 12. The rockingr of thc lever L brings one ot' theshoulders of its hub 32 in forcible contact with the nose ot the hookedend of the catch K `compelling it to rock outward against the force ofits spring 31 until said nose is no longer supported by the hub when thebed bottom and the catch K drop into the inclined position shown bydotted lines Fig.10 under the weight of the occupant.

In the return of the bed bottom to its normal position it is notnecessary to reset the trip arm, but the lever L may remain in its downposition so that the catch may hook over onto the shouldered hub, thusbeing ettectually sustained. Vhen the trip is to be reset the lever willsimply be rocked to its vertical position without disturbing the catch,the latter and the bed bottom lifting slightly as the shoulders of thehub pass beneath the nose in rocking the lever.

In Figs. 15 and 16 another slight modification ot the invention isshown, wherein the lever L is provided with a hub 32, 32, having arecess or depression in its surface, and being of eccentric or cam formwith respect to the pivot of said lever. In the normal position of theparts as shown in full lines in Fig. 15, the hooked end of the catch Krests upon the cam with its nose in substantial alignment with therecess in said hub; the strain of the parts being substantially ornearly vertical through the pivots ot the catch K and lever L', and thusthere is no strain upon the tripping arm 35 and the pawl 37. Theeccentric ot' the hub is so arranged that its weight preponderates toone side of the lever L so that when the tripping arm 35 raises the pawl37 by the loosening of the cord 8, as in the other instances, the leverL' will be free to fall in the direction indicated by the arrow, and assoon as the notch or de pression in the eccentric hub 32 meets the noseof the hooked end of the catch K', the catch is bodily rocked from olfthe hub into the position shown in dotted lines so that the bed bottomand catch fall, as indicated also by dotted lines in said gures. In thiscase gravity is depended upon for the movement of the lever L', insteadof using the spring as in Fig. 12.

From the foregoing it will be understood that the invention is notlimited to the particular constructions shown, but that quite widely(littering forms may be used without departing from its essentialcharacteristics.

In each of the constructions shown the connecting cord 8 between thewinding key and the trip is adapted to wholly leave the winding key orother movable part of the auto- IOO IIO

matic device on a'partial rotation of saidl ing the hook K', a pivotedpawl 37 normally.

engaging with the said lever, an arm 35 pivoted to the end of the leverL and adapted to release it from the pawl 37, analarm clock, and a cordoperatively connecting the arm 15 v35 With the Winding mechanism of theclock,

substantially as set forth. v

In testimony whereof I have hereunto set my hand in the presence of twoWitnesses.
